Well i think on safety, they look at the stats on the number of pple ferried, the number of hours travelled in comparisson with the number of accidents that have happened over a stipulated period of time.eg Air france hav not experienced a major accident since 2005. This is why flying still remain the safest.
On Flight 447, its good to note that the pilot was no newbie having well over 11000 hrs of flying and a 1000 of them with this particular plane that took him and the 227 on board.
 
We pay tribute, and may their souls find peace with their Maker.
